RAILWAY-TRACK STRUCTU RE.

SPECIFICATION forming part of Letters Patent No. 705,131, dated July 22,1902.

Application filed November 19,1901- Serial No. 82,852- (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. PFLIEGER, of J ohnstown,in the county ofOambria and State of Pennsylvania, have invented a new and usefulImprovement in Railway-Track Structures, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, which form a part of this specification.

My invention has relation to railway-track structures of that type whichemploy a wearplate of durable material removably seated in the body ofthe structure and constituting the track-surfaces at the points wheretwo tracks meet or intersect and where the structure is subject to thegreatest wear in service.

The object of my invention is to provide means of novel, simple, andefficient character by means of which the wear-plates may be rigidlysecured in the body of the structure in such a manner as to permit themto be readily removed and replaced when necessary, a further and morespecial object being to avoid the necessity for accurate fitting ormachine-work in the construction and assembling of the parts.

To this end my invention consists in the novelconstruction,combination,and arrangement of parts, all as hereinafterdescribed, and pointed out in the appended claims, reference being hadto the accompanying drawings, in which Figure 1 is a plan View of a frogor crossing embodying my invention; Fig. 2, a side elevation of thesame, and Fig. 3 a section on the line 3 3 of Fig. 1.

In the figures the letter A designates the rail members of thestructure, which are shown as being united by a central body B ,of castmetal, formed with a pocket or recess therein and in which is seated thewear-plate O, which is provided with track-snrfaces and flangeways whichaline with the corresponding surfaces and flangeways of the railmembersa My invention is, however, equally well adapted to structures ofthat type in which the rail members and the central body consist of oneintegral casting in which the pocket for the plate 0 is cored. The sidewalls of the pocket are formed with apertures cored therein and leadingoutwardly from the plate-pocket for the purpose of receiving thefastening members or keys D, which are of approximately Z form, with thelower arms turned upwardly at the extremities, as shown at d in Fig. 3.The plate is seated in its pocket and its upper surface properly alinedwith reference to the tracksurface of the rail members by placing thinshims or blockings underneath it to support it at the proper level. Thefastening members or keys D are then inserted and seated in the mannershown in Fig. 3 with their upper horizontal arms" catching over the edgeportions of the plate and their lower hori- Zontal arms extendingoutwardly from the horizontal apertures in the side walls of the pocket.They are then secured and made to bind the plate to its seat by drivingwedges E between the upturned end portions d and the surface of the bodyB. These wedges draw the fastening members or keys downwardly andoutwardly and cause them to hold the plate securely to its seat withrespect to both lateral and vertical movement, the upper edge portionsof the plate being preferably slightly recessed or grooved out to receive the arms (1 of said members. To provide seats for the wedges E,the body Bis provided with the lugs or bosses E. After the fasteningmembers or keys have thus been seated and secured the space underneaththe plate and between the same and the side walls of its pocket isfilled with spelter or other similar material in the usual manner and asindicated at G.

To remove the plates when necessary, small portions of the adjacentpavement are removed to permit the wedges E to be driven from theirseats, after which by chipping out some of the spelter from around thesaid keys or members they maybe readily withdrawn and the plate pried orlifted from its seat, or,- if desired, by means of a suitable tool theup per arms at of the fastening keys or members can be cut off and theplate unseated.

While I have only shown the invention as applied to a frog orangle-crossing, it is ob vions that it may be applied to other specificstructures in which two or more tracks meet or intersect.

I do not wish to limitmyself to the exact construction and arrangementwhich I have herein shown and described, as it is obvious that slightchanges may be made in the details thereof without departing from thespirit and scope of my invention as claimed. I

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a track structure, the combination with a wear-plate seated in apocket in the structure, of fastening members or keys arranged to gripthe side portions of said plate and having arms extending outwardlythrough the side walls of the pocket, and Wedges or the like engagingsaid arms and securing the said members or keys in gripping engagementwith the plate.

2. In a track structure, the combination with a wear-plate seated in apocket in the structure, of means for securing said plate in its seat,consisting of angular fastening members or keys engaging the plate andextending outwardly through the side walls of the pocket, and wedgesdriven between said members or keys and the body of the structure.

3. In a railway-track structure, the combination with a body portionhaving a pocket therein and apertures leading outwardly from the pocketthrough its side walls, of a wearplate seated in said pocket, andapproximately Z-shaped fastening members seated between the side of theplate and the walls of the pocket, with their upper arms engaging theplate and their lower arms extending outwardly through said aperturesand secured by wedges.

4. In a railway-track structure, the combination with a wear-plateseated in a pocket in the body of the structure, of means for fasteningsaid plate consisting of angular, ap proximately 2 shaped keys, whoseupper arms grip the plate and whose lower arms extend outwardly throughthe side walls of the pocket and are turned upwardly at their ends, andwedges driven between said upturned ends and the body of the structure.

5. In a railway-track structure, the combination with the body portionhaving a pocket, and apertures leading outwardly from said pocketthrough its side Walls, of a wear-plate seated in said pocket, and thefastening keys or members D having the arms cl engaging the plate, thearms extending outwardly through said apertures and terminating in theupturned ends 01, and the wedges E driven between said upturned ends dand the body of the structure.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
